The trusted way to design, build & buy a home in Oman.

eBinaa connects Omani homeowners with verified architects, contractors and developers across three journeys — Design, Build and Buy. Bilingual (English / Arabic RTL), free for homeowners, integrated with Oman Housing Bank, and built on standardized contracts and stage-based payments. I led the end-to-end product experience.

— 01 / Overview

A whole home journey — design, build & buy.

eBinaa connects homeowners in Oman with verified architects, contractors and developers — from designing a home, to building it under a structured contract with stage-based payments, to buying a ready or off-plan property. It's free for owners, bilingual (English / Arabic), and covers all nine governorates.

The product had one organizing idea: remove risk from the biggest purchase of someone's life. Trust here isn't a marketing word — it's built into verified company profiles, standardized contracts, a 5% retention policy, and payments that only release as real work is completed.

— 02 / The challenge

Building a home meant trusting strangers with your life savings.

One. No way to verify reputation. Contractors and architects were judged on word of mouth — there was no reliable record of who actually delivered quality work.

Two. Informal deals, no protection. Agreements were verbal and money was often paid upfront, so if a contractor abandoned the job mid-way, the owner had little recourse and real losses.

Three. A scattered, invisible process. Design, contracting, permitting and buying lived in disconnected places — with no progress visibility, no easy way to compare firms, and limited access to housing finance.

— 03 / Understanding the user

Before designing, I mapped who we were really designing for.

The platform serves homeowners, companies and partners — but the homeowner is the centre of gravity. I built the design around one primary persona: an Omani planning to build a home on their granted land, and the firms and institutions they have to learn to trust.

— Built fromProduct context · ebinaa.info · Oman home-building culture
— Artifact1 primary persona + secondary actors
— Pressure-tested againstCompanies · Oman Housing Bank · MoCIIP

A note on rigor: the primary persona is synthesized from eBinaa's product context and Oman's land-grant building culture rather than a formal interview study, then pressure-tested against the firms and partners an owner relies on. It gave every later decision a person to design for.

Goals
  • Build a quality home within budget
  • Know exactly who to trust
  • See progress without chasing anyone
Pain points
  • Can't verify a firm's track record
  • Fears overpaying and abandonment
  • Process scattered across people & paper

“This is my life's biggest investment — I need to know the people I'm trusting are real.”

What they need
  • Companies: reach serious, ready owners
  • Oman Housing Bank: connect buyers to finance
  • MoCIIP: regulatory credibility & oversight
Friction
  • Hard to reach owners ready to commit
  • No standard, enforceable contract
  • The trust gap cuts both ways

“Owners won't commit until they believe the firm — and the contract — are real.”

Trust is the #1 barrier.

— 02

Money feels unsafe.

Led to → standardized contracts, a 5% retention policy, and payments released stage by stage.

— 03

The journey is scattered.

Led to → one platform across Design, Build and Buy, with a built-in project management tool.

— 04 / Defining the problem

It all collapsed into one question.

The research pointed one way: eBinaa wouldn't win or lose on features — it would win or lose on trust. A homeowner had to believe the company was real, the contract was fair, and the money was safe before they'd commit to anything.

— The questionHow might we give homeowners in Oman one trusted place to design, build and buy a home — where every company is verified, every contract is fair, and every payment follows real, completed work?

— Principle 01

Trust, made structural.

Verification, contracts, retention and staged payments are designed into the product — not promised in copy.

— Principle 02

Design lifecycles, not screens.

Every project is an honest state machine — submit, contract, build, pay, hand over — with no dead ends and no guessing.

— Principle 03

Bilingual by mirror.

Arabic RTL is designed as a complete right-to-left mirror, not a translation bolted on at the end.

— 05 / My role

What I owned, end to end.

01 — IA

02 — Flows

03 — System

A trust-first component library: company cards, comparison tables, contract steps, filters, navigation.

— 06 / Goals

What success looks like, on both sides.

Every design decision answered to two scoreboards at once — the platform's need to grow a verified, transacting marketplace (it monetizes from the business side), and the homeowner's need to design, build or buy with total confidence.

Business goals

Grow the verified marketplace.

Make verified firms and fair, contracted projects the norm — and the reason companies pay to be on the platform.

— 07 / The big idea

Trust, made structural.

eBinaa's whole reason to exist is trust. Rather than asking homeowners to take a leap of faith, the design builds trust into the mechanics — who you work with, the contract you sign, and how the money moves.

Verified companiesRatings, completed projects, engineers and minimum price — shown up front.
Standardized contractsClear technical & administrative terms protect both sides.
5% retention policyExit a job mid-way and you bear the cost — abandonment is disincentivized.

— 08 / Information architecture

Three journeys, one home.

The product is organized around three top-level services — Design, Build and Buy — plus the homeowner's account and a project management tool. The IA mirrors the real journey: design your home, build it under contract, or buy one ready-made — with trust signals one tap away.

— 09 / Bilingual, by mirror

Every screen speaks two languages.

Arabic isn't a translation bolted on — it's a complete right-to-left mirror: navigation on the right, mirrored cards, and a fully localized vocabulary. Designing both directions kept the layout, component and spacing systems honest.

— 10 / The modules

Four things you do here.

Design a home, build it under contract, buy one ready-made, and track it all the way — each module is a surface in the platform, and each one is held to the same standard of trust.

Design
Browse and compare verified architectural firms — architectural, exterior 3D, landscape and MEP design.
Build
Submit a project and get matched with contractors and a supervision consultant — structure-only or turn-key, under a structured contract.
Buy
A marketplace of new residential developments across Oman, with Oman Housing Bank finance options.
Project management
Track milestones, stage approvals and progress in real time, with payments released stage by stage.
— 11 / Signature flow: opportunity → payment

From empty plot to handover. Eight honest stages.

I modeled the homeowner's build journey as a state machine rather than a set of screens — every stage has one clear status, and money only moves when real work is verified.

01
Submit
The owner submits the plot, drawing status and build type.
02
Match
eBinaa matches verified contractors and a supervision consultant.
03
Compare
The owner compares offers side by side and chooses a firm.
04
Contract
A standardized construction contract is generated and signed.
05
Retention
5% of the value is retained, so abandoning the job carries a cost.
06
Build
Work begins; the project management tool tracks every milestone.
07
Stage pay
Payment releases only after each construction stage is verified.
08
Handover
The home is completed and handed over — structure or turn-key.

One empty plot. eBinaa carried it all the way to the keys.

— 12 / Low-fi wireframes

Structure in grayscale, first.

Before any colour touched the screen, I wireframed both surfaces in grayscale — the contractor's desktop workspace and the homeowner's mobile app — to settle hierarchy and the repeating card-and-status pattern that makes the whole platform feel predictable.

Grayscale wireframes built to the exact layout of the shipped screens — four contractor desktop surfaces and six homeowner / partner mobile screens — settled before any colour.

— 13 / Design system

Calm, trustworthy, navy & green.

eBinaa runs on a calm, trustworthy system — deep navy as the primary, a bright green for actions and confirmation, on white — with semantic amber and red reserved for caution. Everything is defined as shared styles so a multi-service, bilingual product stays consistent, in both directions.

— 14 / Final screens

The other side — the company workspace.

Trust runs both ways. While homeowners move through Design · Build · Buy on mobile, verified companies run their whole business from a desktop workspace — discovering opportunities, bidding, signing the contract, managing projects, proving credibility through a verification-driven profile, and collecting moderated reviews. The same status language carries across every surface, in English and Arabic.

— 16 / Validation

How I'd prove the bets actually work.

Live metrics sit outside the brief, so I won't claim numbers I never measured. Instead, every risky decision ships with a validation plan: a clear hypothesis, the method I'd run, and the one signal that would tell me I was right. Drop your real results into the band below.

— Test 01 · Trust signals

Verified profiles make owners confident to reach out.

Method
First-click test — “which firm would you trust, and why?”
Signal

— Test 02 · Compare vs browse

The right view to choose a firm.

Method
Timed comparison & discovery tasks across both views
Signal
Tables faster for comparison, cards faster for discovery
— Test 03 · Build setup

An owner can submit a project without help.

Method
Moderated project-submission task

Trust isn't a feature you add at the end — it has to be built into how the money and the work move.

— Husain Al-Asfoor, Founder of eBinaa
— 18 / Reflection

What the system taught me.

— 01

Trust is structural, not cosmetic.

Verification, fair contracts and staged money did more for confidence than any amount of reassuring copy.

— 02

Trust is a UX problem.

Making firms' track records and contract terms legible turned an act of faith into an informed decision.

— 03

Design lifecycles, not screens.

Modeling the build journey as an honest state machine — submit → contract → stage-pay → handover — prevented dead ends.
